I am looking for any information on the marriage or death of the following. George Graham whom married Mary Coulthard. On or before 1867 in Northumberland. I have copies of their daughter Margaret Ann Graham whom was born 15 Apr 1867 in Low Houses, Allendale,NBL and married March 17, 1900 in District: Auckland County: Durham both list the parents as George Graham and Mary Coulthard on these cert. I have been unable to locate anything on this couple. I am hoping that some one will have heard or known of them. This has been a brick wall for me in my Graham/Bell research. Thanks very much. Warm Regards, Edward Zuellig Michigan
